| description | Retrieve current library documentation and code examples from Context7. Use when looking up library APIs, "docs", specific library versions, or "how to use [library]". Prefer over training knowledge for library-specific questions. Do not use for general programming concepts. |
Context7 Documentation Lookup
Retrieve current documentation and code examples for any programming library directly from the source.
Usage
Use the Python script at scripts/context7.py.
Get Documentation
python scripts/context7.py docs \
--library-id /facebook/react --query "useEffect cleanup function"
python scripts/context7.py docs \
--library-id /vercel/next.js/v15.1.8 --query "app router middleware"
Search Libraries
Use search only when the library ID is unknown:
python scripts/context7.py search \
--library react --query "hooks"
Query Tips
- Use detailed, natural language queries for better results
- Good:
"How to implement authentication with middleware"
- Bad:
"auth"
Common Library IDs
| Library | ID |
|---|
| React | /facebook/react |
| Next.js | /vercel/next.js |
| TailwindCSS | /tailwindlabs/tailwindcss |
| Expo | /expo/expo |
| ORPC | middleapi/orpc |
Rules
- Query docs directly when you know the library ID
- Use search only if unsure about the library ID
- Use specific version IDs for consistent results (e.g.,
/vercel/next.js/v15.1.8)
- Use
--format json for structured output
